A maintenance controller describes the mis-communications surrounding an inflight md-80 left engine ...

Narrative:

Called maintenance for information; heard in-flight shut down. After [phone] call found engine was pulled to idle and not shut down due to low oil pressure. Maintenance found faulty oil tank cap and leaking oil line to oil filter differential pressure switch. On return to work next day; reviewed the write-ups in logbook after it was inputed into our [maintenance] computer and noted crew reported oil pressure dropped to 20 psi. Amm states any oil pressure below 34 psi requires inspection of oil system components which is an engine replacement. I had aircraft stopped in [at another station] for engine replacement. This report is information on my actions in this matter.
